    摘要： An organic light-emitting device includes a first electrode, a second electrode, and an organic layer interposed between the first electrode and the second electrode. The organic layer includes at least a light-emitting layer, wherein the light-emitting layer includes a plurality of compounds which have individually a light-emitting repeating unit and at least one of a hole-transporting repeating unit and an electron-transporting repeating unit and which are different in the molar ratio of the light-emitting repeating unit and at least one of the hole-transporting repeating unit and the electron-transporting repeating unit, and wherein the plurality of the compounds are stacked so that the molar ratio of the hole-transporting repeating unit may decrease and/or the molar ratio of the electron-transporting repeating unit may increase in the direction from the first electrode toward the second electrode. The hole transport capability of the light-emitting layer decreases in the direction from the first electrode toward the second electrode and the electron transport capability of the light-emitting layer decreases in the direction from the second electrode to the first electrode. Therefore, hole transport and electron transport are equilibrated, thereby ensuring high efficiency and long lifetime.
